Cmake中的INFERENCE_ENGINE_LIB未设置错误

Question

我尝试使用英特尔movidius Myriad X VPU在我的树莓派4中运行gender_age示例(https://github.com/movidius/ncappzoo/tree/master/apps/gender_age)，但出现错误

我按照教程https://software.intel.com/en-us/articles/get-started-with-neural-compute-stick操作，直到下一步: ncappzoo标题is my error

Intel OpenVINO environment is already set!

本例中的CMake文件取决于OpenVino环境变量。假设您已经安装了OpenVino，使用它通常需要在当前命令提示符中或在系统环境变量中永久设置OpenVino environment variables。正如this answer所描述的，您可以分别设置它们，或者在继续执行cmake命令之前运行环境变量脚本：

> C:/path/to/your/openvino/opencv/setupvars.bat

在命令提示符中运行此命令后，命令cmake ..应该能够访问这些环境变量(特别是INTEL_CVSDK_DIR)并成功生成buildsystem。然后，您可以使用make编译该示例。
